To all 207mm #may concern Be it known `that I, DAVID BRIGKMAN, a citizen of the United States, residing `at Los Angeles, in the county of Los Angeles and State of California, have inventednevv and useful Improvements in Gas-Burners, of Which the `following is a specification.

M r burner especially adapted `for bake ovens, and my invention consists tures herein shown,

Figure l isa fragmentary side elevation of a bake oven showing ing the principles of tion for use.

Fig. 2 is a fragmentary end elevation of the bake oven and showing thegas supply pipe andregulator valves of the burner.

Fig. 3 is an enlarged top plan view of the burner, and looking inthe direction ndi myrinvention, in posi catedb the arrow 3 in Fil 2 arts bein" n '5 g 7 p g"casing 31 at the bottom of the casing above shown in section.

Fig. 4 is a vertical cross sectional detail on the line 4-4 in Fig. 3.

Fig. 5 is a vertical cross section on the line 5-5 in Fig. 4.

The shell 1 of the bake oven rests upon a foundation 2, and a burner opening 3 is formed in the end Wal1-4 of the shell 1, there eing a sliding door 5 for closing the opening 3. A passage 6 is cut through the end Wall 4 at one side of the opening 3 and communicating with th'e opening. The opening 3 is large enough to allow the burner 7 to pass through the opening and the burner pipes 8 pass through the passage 6. The pipes 8 are connected to the supply pipe 9 by union 10, there being a stop cock 11 in the pipe 9 so that the stop cock 11 may be closed, the union 10 disconnected and the burner 7 and pipes 8 removed from the bake oven for cleaning, repairing, and so on.

T e burner 7 consists of the independent sections 12, 13, 14 and 15, eachsection having an independent feed pipe 16, 17, 18 and 19, each feed pipe being controlled by a separate regulating valve 20, 21, 22 and 23, the union 10 is connected to a pipe nipple 24, a T 25 is connected tothe nipple 24, and the valve 23 is connected to the side outlet of the T 25. A second T 26 is connected to the end outlet of the T 25 and the valve 22 is connected to the side outlet of the T 26. A third T 27 is connected to the endoutlet of the T 26, and the valve 21 is connected to object is to make `an improved gasV of the novel fea-f described and claimed.

mounted upon legs 30, said frame 29 being large enough lto support` and form a base for the four burner sections l2, 13, 14 and 15. Theburner section 12 has a rectangular s'heetmetal casing 3lnand vertical partitions 32`and 33 equally spaced apart relative to the ends of the casing. `A sheet 34 of Woven Wire ismounted in position to form a bottomfor the Vcasing13l and the `bottom rests upon'the horizont-allianges 35 and 36 of the angle iron fra1ne29. `A sheet 37 of Woven Wirecis stretchedover the top of the casing 31 and heldin place by a `binding 33. The section 39 ofthe feed pipelwhas `gas discharge orifices 40, 41, and 42, and the section 39 is inserted transversely throughthe the Woven wire 34Vand through the angle ironfraine 29, and a cap 43 placed upon the dead end of the pipe section.

In a like manner, the pipe sections 44, 45 and 46, are mounted in the burner sections 13, 14 and 15.

en the valve 20, opened, the gas -vvill flow through the orifices 40, 4l and 42 and discharge up- Wardly and draw the air through the `Woven Wire 34 and the mixture will pass upwardly through the Woven Wire 37 and burn on top of the Woven Wire 37. The woven Wire 37 has considerable area, the casing 31 is height, and the discharge of the gas through the draft which will draw the fresh air through the Woven Wire 34`in abundance to produce a perfect mixture, and the Woven Wire 37 is ne enough so that the flame will not pass through the Woven Wire and burn back to the orifices. Each section 12, 13, 14 and 15 of the burner is substantially alike, and each section may be operated independently of the other section and each section may be Hnely regulated by the valves 20, 21,

for instance, is
